...select which helpers to use. This gives drivers an easy way to reuse a lot of the code in the helpers while at the same time allowing them to provide their own implementation for other functions in struct dma_buf_ops.

Add drm_device argument to drm_prime_pages_to_sg(), so we can call dma_max_mapping_size() to figure the segment size limit and call into __sg_alloc_table_from_pages() with the correct limit. This fixes virtio-gpu with sev. Possibly it'll fix other bugs too given that drm seems to totaly ignore segment size limits so far ... v2:...

Allow user space to provide an explicit sync fence fd when exporting a dma-buf from gem handle. The fence will be stored as the explicit fence to the reservation object.

...bly useful. So I think a better approach would be to add this as ioctls to the dma-buf fd itself. Then you can also add a "give me the fence(s) for this dma_buf" ioctl, which is useful for interop the other way round (i.e. implicit -> explicit). -Daniel > --- > drivers/gpu/drm/drm_prime.c | 41 +++++++++++++++++++++++++++++++++-------- > include/uapi/drm/drm.h | 9 ++++++++- > 2 files changed, 41 insertions(+), 9 deletions(-) > > diff --git a/drivers/gpu/drm/drm_prime.c b/drivers/gpu/drm/drm_prime.c > index 2807a77..c69df2e 100644 > --- a/drivers/gpu/drm/d...
